Agnix is an Open-Source project, which has been founded to provide an educational, network operating system kernel. Agnix is an extended kernel, written in pure C code. It is ideal starting point to learn about operating system kernel architecture.

The mission of the Apache Portable Runtime (APR) is to provide a free library of C data structures and routines, forming a system portability layer to as many operating systems as possible, including Unices, MS Win32, BeOS and OS/2.

smart_ptr is a smart pointer policy class that can use different ownership logic and semantic polices, which allows the developer to get the best performance and/or interface for a particular requirement.

The fksec package is a set of C++ classes to have a useful alternative to the Security APIs From Hell, the ones that were introduced with NT 4.0 and serve no useful purpose except to make our lives miserable with their bugginess.

FOX is a C++ based Toolkit for developing portable graphical user interfaces. It offers a wide, and growing, collection of controls, and provides state of the art facilities such as drag and drop, selection, as well as OpenGL widgets for 3D graphical manipulation.

FreeImage is an Open Source library project for developers who would like to support popular graphics image formats like BMP, JPEG, TIFF and PCX and others as needed by today's multimedia applications.

GDAL is a translator library for Geospatial data formats (raster and vector) that is released under an Open Source license. As a library, it presents a single abstract data model to the calling application for all supported formats.

A collection of C++ classes for general and communication oriented programming. All classes manage their own memory and provide bounds checking to make life easier for the programmer. Most of the classes are portable to Linux and Windows. HOOPLE is the home of the Octopus design pattern and the CROMP network protocol.

The jungle graphics library is a set of C++ classes that are either contributed directly from a researcher in the lab or are the hybrid of similar classes developed individually by separate researchers. The aim is to have a common set of general classes that are useful for research in computer graphics.

KMyMoney is the Personal Finance Manager for KDE. It operates similar to MS-Money, supports different account types, categorisation of expenses and incomes, reconciliation of bank accounts, QIF import/export and much more.

Metamod is a plugin/DLL manager that sits between the Half-Life Engine and an HL Game mod, allowing the dynamic loading/unloading of mod-like DLL plugins to add functionality to the HL server or game mod.

MiniGUI is an LGPLed free software project that aims to provide a fast, stable, and lightweight Graphics User Interface support system, which is especially fit for real-time embedded systems based on Linux.

OpendTect is an open source seismic interpretation environment that can be used to process, visualize and interpret multi-volume seismic data and to develop innovative interpretation tools via an easy plugin system.

OpenPTC is a third-generation standard for cross-platform low-level graphics access. OpenPTC provides programmers with an array of pixels to draw to and the means to quickly output these pixels to the display device. It also provides some other useful features such as basic keyboard input and a highresolution timer.

QtVu, pronounced CuteView, is an image viewer for The X Window System. It was developed using Linux, but I hope it'll run on other UNIX variants as well. QtVu is heavily inspired by ACD Systems' excellent ACDSee.

The STAR experiment is Nuclear Physics experiment part of the RHIC project, which has been a leading force to the study of the Quark Gluon Plasma, providing access to the most fundamental building blocks of nature known so far: quarks and gluons.

A class library for dealing with asynchronousness using an eventprocessing model instead of a multi-threading model. Also enables the building of complex protocols out of simple pieces that can be plugged into each other.

"SuperMix" is a software library written to aid in the calculation and optimization of the signal and noise performance of high-frequency circuits, especially those including superconductors and superconductingtunnel junctions.

Xapian is a high performance search engine library. It implements theprobabilistic model of information retrieval, and is designed for usein applications ranging from full scale Web search engines to searchingthrough email archives.
